Redox properties and stability constants of anion complexes. An electrochemical study of the complexation of metal hexacyanide anions by polyammonium macrocyclic receptor molecules

Abstract

Electrochemical studies on macrocyclic complexes of M(CN)₆ ^4–(M = Fe, Ru) anions indicate a 1 : 1 stoicheiometry and monoelectronic, reversible oxidation for these complexes, and illustrate the control of redox potential of anions by complexation with appropriate receptor molecules.
